Template:Sigbox raw

Usage:  to put the text in a box.

You can try  to put a template-ized sig inside the box, but sigbox is simpler.

One use for this could be to put  and   around your sig in the template itself (so you can easily see its size in Show Preview). The  bit protects it from being confused by any   signs in the sig (it still will get confused if you have any   signs outside of links), but you can use ! for those.
